The cause of the algae blooms

Lake Erie’s algae blooms are caused by runoff pollution. This type of pollution occurs when rainfall washes fertilizer and manure spread on large farm fields into streams that flow into Lake Erie. This fuels a bumper crop of algae each year that can make water toxic to fish, wildlife, and people.

Algae blooms are preventable

Mandatory rules needed

Unfortunately, very few rules are in place to limit runoff pollution from big farms. It is time for mandatory regulations to reduce the amount of runoff pollution allowed to flow into Lake Erie. New regulations will reduce Lake Erie’s blooms, restore the lake, and ensure safe, clean drinking water for our families.
